摘要

An o-bromophenylzinc compound, first prepared in an excellent yield by the reaction of o- bromoiodobenzene with zinc powder in THF, was found to be an efficient synthetic equivalent of o-phenylene 1-anion 2-cation in Pd (0)-catalyzed stepwise cross-coupling reactions, affording unsymmetrically 1, 2-disubstituted benzenes with diverse substitution patterns and with a variety of functional groups.
